Abstract (en)
Provided is an ultrasonic liquid sensing transducer (10) comprising a rigid supporting frame (12) and a piezoelectric element (14) mounted on the supporting frame (12). The supporting frame (12) is adapted to support a peripheral section (14a) of the piezoelectric element (14) and to provide a void (16) overlapping with a central section (14b) of the piezoelectric element (14).
